Romanian Eagle

While the world was talking about Eder's ascension to the Bulgarian throne, at a heavily guarded air base outside Lviv, a group of people in blue overalls were bustling in front of a bizarre-looking plane.

It is said that this plane is weird because it does not even have the most basic propeller, and the entire plane has no propeller installed at all.

Such a strange-looking plane also attracted the onlookers of many air force base personnel.

Dolev, do you think this thing can fly?

In the crowd of onlookers, a base personnel wearing a flight jacket asked about his colleagues.

The called Doleph shrugged his shoulders and replied with a look of don't ask me. Who knows. But I heard that this is the latest achievement of the Lviv branch of the Power Research Institute. Maybe it can fly.

After speaking, Dolef continued to speak. But if you let me fly, I wouldn't dare.

That's right, Dolef was not at all worried about this weird-looking plane. Even though he was known for his boldness in the Fourth Air Wing, he refused to try a propellerless plane like this.

There are many people like him in the base, and the focus of everyone's discussion is whether this thing can fly. And this kind of discussion will inevitably reach the ears of the busy staff who are in front of this strange plane. Faced with these comments, Valksu, the project leader, was not surprised at all.

Valksu is the head of the Power R\u0026D Center, the jet engine project. He graduated from the Department of Power Engineering of the University of Bucharest, and was recruited by the National Power Laboratory with his excellent results. After working in the power laboratory for several years, Valkesu developed a strong interest in jet engines.

In fact, the development of jet aviation power is very early. Since the 17th century, some people have tried to use steam power or internal combustion engines to realize jet engines that can be used, such as the Dutch physicist Huygens.

Henry Coanda also experimented with jets as early as 1910, by using a conventional piston engine to drive a fan to compress the air and ignite gas propulsion in the space behind, known as a thermal jet engine. Although this kind of engine has a simple structure, it is heavy, has insufficient thrust, and has poor practicability.

Of course, the development of jet engines did not end with failure, but continued.

In 1915, Albert Von of the Austro-Hungarian Empire devised a device that used gas and compressed air to increase the range of artillery shells. This device provides thrust by compressing and igniting the airflow when the projectile is flying at high speed through a variable-section air inlet.

However, the Austro-Hungarian army ultimately did not adopt its design, so he registered a patent for the scramjet in Germany in 1928 and passed it in 1932. Thus was born the ramjet.

In 1921, Frenchman Maxime Guillaume patented the first jet engine. His design resembles an axial jet engine.

In 1928, Frank Whittle of the Royal Air Force Academy in Cromwell, England, proposed a new jet engine design. In January 1930, Whittle filed a patent for the design of the jet engine, which was granted in 1932. Whittle's design featured a two-stage axial compressor in front of a large centrifugal compressor, driven by a turbine. Whittle later removed the previous axial compressor and used a larger centrifugal compressor.

Since jet engines continue to develop abroad, as the main power research unit in Romania, it is impossible for the National Power Laboratory to turn a blind eye to it. Jet engines are also being developed at the National Power Laboratory, under the auspices of old dean Rudolf Diesel.

It needs to be explained here that Rudolf Diesel has long stopped developing diesel engines. Already in his 70s, he has already made a name for himself with the widespread use of diesel engines. At present, his main disciples continue to develop this diesel engine.

The development of jet engines,

It was handed over to Valksu, who had the most research on jets in the power laboratory. And this Valkesu lived up to expectations, and finally successfully developed a new jet engine in cooperation with his German colleague Hans von Oran (the result of Rhodes cooperation).

During the ground test, the axial-flow jet engine produced a thrust of 5 kN, which surprised the researchers of the two countries. This means that this jet engine has reached the standard of use. Since it has reached the practical standard, it is simply too uncomfortable not to fly.

So under the impetus of Valksu, a new aircraft specially flight-tested for this engine was born. The new aircraft, designated F-101, has a total length of 9.4 meters and uses a lower wing. Because the engine is in the abdomen, it looks a bit like a blowing puffer fish, and it does not have the slenderness of other propeller aircraft at all.

This is also the reason why most of the base do not like it. The appearance is really important for the aircraft.

But this is not so important to Valkssu and Hans von Oran today. First of all, they have to make the plane fly.

How's the inspection going?

Valksu, who had sweaty palms, asked his staff. This is the last check before the flight. If the plane can't fly, I can't do it myself. You must know that the power laboratory is not only developing jet engines, but the traditional piston engine power laboratory is developing several models. Such as a 900-horsepower star-shaped air-cooled engine, a 1200-horsepower straight-cylinder liquid-cooled engine, and a 1350-horsepower V-type liquid-cooled engine, it can be said that there are many kinds of aero engines.

Even many projects not only pay attention to the work at hand, but also take the opportunity to prepare for the next pre-research in advance. For example, he knew that the 900-horsepower radial air-cooled engine project in charge of Kriside was doing preliminary research for the next 1,200 horsepower.

Not to mention the gasoline and diesel engines that are currently the flagship products of the Power Lab. These two engines rely on the prosperous automobile industry and Rudolf Diesel's outstanding ability, respectively, so that the power laboratory can obtain sufficient funds. Although the funds are sufficient, competition is essential. Everyone wants to have no shortage of funds for their projects, which needs to be reflected in the results. And getting the world's first jet to fly is Valksu's top priority, so it's no wonder he's not nervous.

The engine is fine.

The instrumentation is all right.

The oil supply system is normal.

...

As the staff checked the normal reports one after another, Valksu calmed down, and then he patted the test pilot next to him on the shoulder.

Rolix, let's get started.

The Rolix test pilot, who was wearing a parachute, nodded in response and said with a smile. Don't worry, I will fly it back.

The F-101 jet began to glide across the ground faster and faster as test pilots boarded the plane and fired up its engines.

As the numbers on the meter turn larger and larger,

Test pilot Rolix jerked the lever and felt the plane light up. Experienced he knew that the plane left the ground, and then he increased the horsepower to pull the plane up.

After seeing the plane take off, the base was full of people. Many melon eaters sighed.

Look, this plane is really flying.

I didn't expect it, it really flew.

And as a tester, it is even more cheering.

We made it.

Valksu also happily hugged his colleague O'an after seeing the plane leave the ground. It was a success this time.

The joy of success moves everyone. It is not easy, so many years of hard work and hard work day and night have been released at this moment. This peculiar plane soaring in the sky also proved that their hard work and efforts were not in vain.

Okay, let's continue to test it, everyone cheers up.

With Valksu's words, the testers present immediately recovered. Flying is just the first step in the Long March, and they will also conduct various tests on it.

In the next test, the performance of the world's first jet aircraft was very surprising, both in speed and climb, it far surpassed the piston aircraft. However, the main reason that restricts its soaring in the sky at present is the service life of the engine and the high cost.

The actual situation of a 28-hour overhaul makes it unpractical, and the cost is too expensive to make this engine only test for jet flight.

But Valksu and Oran are not worried at all about this, it's like the world's first aircraft. There is nothing to worry about if it is not practical in a short time. As long as the investment in research and development is increased, there will be a day when it will bear fruit in the future.
